To all whom t may concern.'

Be it known that we, Louis B. GoLDBnnG and NATHAN GOLDBERG, citizens ofthe United States, residing at the city and county of Denver and Stateof Colorado, have invented certain new and useful Improvements in Framesfor Tent-Openings; and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and t0 the charactersof reference marked thereon, which form a part of this specification.

Our invention relates generally speaking to improvements in frames fortent openings, and consists of a metallic structure adapted to beapplied wherever it may be necessary to form an opening in a tent,simply by cutting va slit in the tent fabric, spreading the fabric apartand inserting the frame, the fabric on opposite sides of the slit, beingreceived by the frame but spaced sufficiently for the required opening,the frame consisting of two coperating parts placed adjacent each otherand adapted to clamp the canvas or tent fabric around the opening. Thedevice is more especially intended for use where it-is desired to pass astovepipe through the tent wall and forthis reason, the device might beappropriately termed a tent thimble for stovepipes. y

In our improved construction the two superposed plates or members, areconnected with each other by means of,` pins which are swivele'd in onemember and pass through openings in the other member, these pins :beingprovided with elongated heads which one member of the frame is slottedto receive when the heads are properly adiuste'd. As these heads arerelatively thin, they lock the two plates together when so adjustedthat'their heads form; suitable angles with the direction of the slotsor occupy positions crosswise thereof. An important feature of ourimprovement, consists' in the employment of a spacingl flangeimmediately adjacent the central or main opening formed in the twoplates, this flange making it impossible for the tent fabric or canvasto work out from between the two plates adjacent the stovepipe,consequently, absolutely protecting the canvas from contact with thestovepipe. lt is evident =thatif by any: pos- Sani-Ly er fabric ef thewat Specification of Letterslatent..

which is 'held between the two frame members raround the centralopening, should work out of the plates of the frame in such a manner asto come in contact with the hot stovepipe, that lire would result. Ourobject is to completely overcome this difiiculty.

Having briefly outlined our improvement, we will proce-ed to describethe same in detail, reference being made to the accompanying'drawing, inwhich is illustrated an embodiment thereof.l ln this drawing,-

Figure l is a plan view of our improved device, showing the two membersin the assembled relation and applied to a tent in such amanner as toleave an opening for a stovepipe in the frame.

Fig. Q'is a similar view of one member of the device, or the member thatis outermost when the device is applied.

Fig. 3 is a sectional view taken through the device on the line 3 3,Fig..l, the position of the stovepipe being indicated by dotted lines.

Fig. l is a sectional view of the frame f showing the two parts inl theassembled relation, the tent fabric, however, being omitted and theparts shown on a larger scale than in Figs. 1,2 and 3.

Fig. 5 is a similar view of the outer meme ber of the device which. isshown in detail and on the same scale as in Fig. 4. Fig. 6 is a Viewsimilar to Fig. 5 but illustrating the coperating member.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate one member of 'our improved frame, and 6 thecoperating member. These members are preferably elongated and having thegeneral outline of an oblique-angled parallelogram whose horizontaldimension is considerably shorter than its vertical dimension taken atright angles thereto, the measurements being' central in each case. Itwill be evident, yhowever, that the outline or particular design of thetwo members is not very material except so far as appearance isconcerned. In using the terms vertical and horizontal, We are assumingthat the frame is in position and secured to the vertical wall of atent. Hence, these terms are used only for convenience of explanation.The member 5 which is outermost, is provided with a central opening 7which determines the size of theA stovepipe which is to pass therelll@to forma stovepipe opening in the tent. This opening is surroundedeXteriorly by a flange 8. The body portion 9 of this member 5 isequipped with a number of pins 10 which pass through openings formed inthe member, and are swiveled or journaled therein. These pins have flatheads which project interiorly, the bodies of the pins being preferablycylindrical in shape and adapted to fit in openings formed in the twomembers of the frame. As shown in the drawing, there are four of thesepins 10 which are arranged near the outerextremities of vertical andhorizontal lines passed centrally through the device when the latter isin place or supported upon the vertical wall of a tent. The pins, arehowever, set inwardly from the outer edge of the member 5 sufliciently`to allow the tent fabric 12 to overlap the edge of the member asuitable distance to permit securely clamping the tent fabric betweenthel two members when the parts are assembled. This overlapping portionis designated 13 and is best illustrated in Fig. 2 of the drawing. Theedge of this member vis beaded as shown at 14E, this bead coperatingwith a similar bead 15 formed on the corresponding edge of the member 6,the two beads, however, being adjacent and in engagement when the twomembers are in the assembled relation, thus ooperating to form a shallowchamber between the narrow areas of the two members, beyond the swiveledpins, this chamber being of sufficient magnitude to receive the portion13 of the tent fabric which will be somewhat wrinkled, due to the factthat it is assumed that none of the tent fabric is removed when thedevice is applied, the idea. being to simply form a slit in the tentfabric or rip a seam, and separate the free edges of the fabricsuficiently to permit` the employment of the frame. Hence, if it isdesired to remove the frame at any time and place it in anotherposition, the tent fabric may be restored to its normal position andsewed, whereby the opening is closed.

The member 6 is provided with openings 16 whose central portions arelarge enough to receive the bodies or cylindrical portions of theswiveled pins 10 which, as shown in the drawing, consist of ordinarypins with reduced shanksv but to which are applied spacing sleeves 17for purposes of enlargement. The outer extremities. of the pins passthrough washers 18 and are upset for riveting purposes las shown at 19.The openings 16 in the member 6, are elongated in `one, direction toreceive the flat heads 2O of the pins when the latter are properlyadjusted for the purpose. But when these heads are turned to occupy aposition at right angles to that which they occupy when passing throughthe elongated portions 21.

of the opening 16, the two members v5 andl 6 are secured in theassembled relation.

The member 6 has a flange 22 which surrounds the main opening 23therein, this flange engaging the body portion 9 of the member 5 whenthe parts are assembled, this engagement being preferably at aconsiderable distance from the opening 7 as best illustrated in Fig. 1of the drawing. This flange not only spaces the two plates varound themain openings, but also forms a closure, whereby the shallow chamber 24is closed interiorly, and it becomes impossible for any portion of thepart 13 of the tent fabric,

to work toward or come in Contact with the stovepipe, for instance, whenthe device is used as a stovepipe thimble for tents, thus obviating anydanger from fire due to direct- Contact of the tent fabric with the hotstovepipe. As shown in the drawing, the member64 of the frame isprovided with a number of perfor-ations 25, while the flange 22 isprovided with a number of relatively small perforations 26. Theseperforations serve to ventilato the chamber 24 and thus have a tendencyto keep the parts cool, when the stovepipe is hot and the metal'partsbecome heated by heat conductivity or radiation or both.

From the foregoing description, the use as well as the manner ofapplying our improved device will be readily understood. In the firstinstance a seam is opened ora slit formed in the fabric of the tent, ofsuiiicient size for the purpose, the fabric being parted where the slitis formed, sufficiently to allow the member 5 to pass therethrough andengage the fabric on the outside, the free edges of the fabric beingmade to overlap the member on the inside as shown at 13 in Fig. 2. Thepins 10 are so adjusted that when the member 6 is applied, the flatheads 20 of the pins will pass through the elongated portions 21 of theopenings 16 in the member 6. These heads are then turned to occupy aposition preferably at right angles to the extensions 21 of theopenings, inl which event the two frame members are locked securelyinplace, and the portion 13 of the tent fabric tightly clamped between thetwo members, and at the same time prevented from moving inwardly towardthe stovepipe or beyond the flange 22, and as this fiange is itselfconsiderably removed from the opening 7 and consequently from thestovepipe, the tent fabric is at all times. held at a proper distancefrom the stovepipe vto remove all danger from fire by actual contact ofthe fabric with the stovepipe. In the drawing (see Figli), thepositionof thel stovepipe is indicated by dotted lines and the pipe isdesignated by the numeral 28.

As illustrated in the drawing, the plate or member 5 is equipped with anumber of pins 2.9 whose free extremities-are ,adapted t0 engage thecooperating plate or member 6 for spacing purposes when the parts areassembled. These pins also coperate with the pins l0 to maintain thepart 13 of the canvas or tent fabric as far removed as possible from theopening 7 through which the stovepipe passes when the `plates areassembled. These may be employed or not as desired.

Attention is called to the fact that the opening 7 when not employed toreceive a stovepipe, may be covered by a piece of thin, transparentmaterial as isinglass or mica or by a sheet of fine mesh material, thesheet whether of transparent or mesh material being clamped between thetwo members 5 and 6 by the employment of the screw pins 29.
